Study on Failure and Reinforcement Technology of Soft Rock High Slope in Highway Engineering
In order to explore the collapse of the soft rock slope beside a highway,the treatment scheme is given.This paper makes an on-the-spot investigation of the slope along the highway,and the results show that the most efficient slope protection method adopted in the study area is vegetation slope protection(82.0%),and the failure rate of mudstone slope is the highest in the most common weak rock formation.the most common failure modes are surface erosion and shallow landslides.The factors affecting slope failure include insufficient drainage of Rain Water runoff,different rock types and vegetation on the slope surface,slope angle and height.According to the failure characteristics of mud-stone slope,the soil-tire-vegetation reinforcement method is put forward,and the feasibility of the method is verified.
